in connection with the accompanying draw-I ings, is a specification,- like characters oni metal coating or surface which ismoreor less porous, as by so 'doing provislon 1S made 10 the drawings representing Alikeparts. Thisinventionrelates to an improvedartcleof manufacture having =an exterlor metal surface Which is affixed to a iexible' non-metallic foundation or underlying member by 4a layerof asphalt or like bituminous material. The 'found ation member is `flex'- 1blefand non-metallic material, such as felt, paper or fabric, which 1s coated or saturated -with asphalt or like bituminous ma-- terial, 4and in accordance .with .this-.invention is'provi'ded with an exterior surface o r coating of metal, preferably. lead,`zinc, cop@- per or like so-called non -corrodible-metals, which metal'surface is composed of a layer.

of finely divided metal particles whichv4 are embedded in the, asphaltic layer, and an atlditional layer of finelydivided metal particles which vare molecularlyunited With .embedded in the asthe metal particles .phaltic layer.

' The finely d ivided particles of metal formi ing the layer which is embedded lin the asphalt layer are formed by spraying or proj- ,jecting. moltenmetal upon and into the asf.

Whichcon'forms to the contour. of 'thebitu A 'minous' covered brous article and does not v4detrimentally impair the fiexibility' of. the 'fibrous l'ay.1,r,'so that the brous -layerV lWith .the metallized surface 4adhesiyelyjaflixed' thereto by thefbituminous'maiterial may be rolled into convenient form for shipping and applying the same-toa roof, door, siding :or thelikeg ."v`, 'The-metal coatingor surface'maybe made o f-any'desired'- thickness', as .succeeding layers and' molecularly 'l aye1"of'nieta`l particles.

8 Referring to the-drawing 4article or underlying layer tobe'protected, which as 'above stated iscomposed of flexible-fibrousmaterial, such as fabrim'felt, paper and theflike, which is covered on one o rbothA surfaces with a layer b .of 'asphalt or like bituminousA material, or which is Vimpregnated fvvi'th the asphalt. In .the present instance the a is'enveloped 'by the asphalt, layer b, and. the flatter"'is' provided vvithl a lprotective metal S coating vcomposed vof afplurality 'of layers' of finely divided metal,s'uch` as lead,-

sented.. -v The '-metal "layers c, d, are composed of divided metalparticles v.1(),-'12, re

0f metal particles' may be projected upon -united with the underlying surface upon'jthe asphalt layer, but it theasphalt and blistering `of' the metal coat'd other'feature's 'of this invention I a shingle embodying the? parts of .the layers being omitted,

,l a represents thefibrous layer znc,copper1and the like, and in the' present instance' tWo layers c," d are-'- herein repreiii' spectively, which are formed by spraying or projecting molten metal upon the asphalt coated -layer a with any suitable apparatus,

as for instance, substantially'that shown and described in U. S. Patent No. 495,107 dated -April 11, 1893. rfhe finely divided metal particles are' projected ,against the asphalt coated fibrous sheet or layer a while the asphalt coating is in a more or less tacky or yielding lcondition and preferably soontheyretain their original shape, which for sake of distinction, is represented in Fig. 2 as round or spherical, and thus form the underlying or embedded layer c.

VOn the other hand, the metal particles 12 which are projected While hot against the layer cof embedded metal particles while the latter are. in a heated' condition strike the same withV force sufficient to cause the heated metal particles to cohere at their contacting points orsurfaces and become welded or molecularl united and form the metal layer .d which is thus molecularly united or welded to the underlying or embedded metal layer c.

The metal particles 12 comprising the overlying or exterior layer d, are more or less distorted or changed from their original shapev by impact against the particles of the underlying layer c, and `this change or distortion is represented by vthe irregular or other than round shape of the particles comprising the exterior or surface layer as represented in Fig. 2.

It is evident that by going over the asphalt covered sheet or layer a with the finely divided metal particles while the latter are hot a sufficient number of timesor by go ing over the asphalt coated sheet or layer slowly enough a plurality of layers d may be built upon the embedded layer c, to provide the asphalt coated sheet a with a non# porous metal coating composed of the underyin embedded layer c and a plurality of over ying or welded layers d, but it is referred to provide the asphalt coated s eet or layer a with a metal coating which is more or lessv porous for two purposes, to wit, to prevent blistering as above described and to economize in the cost of the protected sheet, which result may be obtained with a single metal layer d welded to the embedded layer c.

The exterior metal surface or coating is firmly afiixed to the asphalt coated sheet a and a highly efiicient article is obtained, which is especially useful for building purposes, and more particularly for roofing and siding purposes, as the underlying sheet or or layer of fibrous material, as the asphalt' coating may be of such character or quality as to possess the-fiexibility desired to retain a firm grip upon the embedded p-ar' ticlesv of the metal coating and thus permit the protected sheet or layer to be rolled up and unrolled, without permitting or causing separat-ion of themetal coating from the asp-halt coated sheet or layer a.

The asphalt coated sheet or layer L of fibrous material having the metal exterior 'surface or` coating dv may be made andv shipped in the form of a roll as represented in Fig. 1, and unrolled into flat form, represented in Fig. 2, orit may be made in shorter lengthsand provided with tabs 20 as shown ill-Fig. 5 to represent a series of connected shingles, or it may be made in still shorter lengths and in the form of individual shingles as represented in Fig. 4.

The metallized flexible fibrous product herein'shown possesses advantages over the ordinary rolled roofing, in that it isl provided with a metal exterior surface which is affixed to the underlying fibrous layer so asy to form a practically permanent metal surface tl1erefor,which is continuous and can be rolled up without liability o'f being separated therefrom and which is fire and vweather resisting, does not disintegrate under the influence of the weather and which can be painted in` any color. By the term asphalt as used in the claims, it is desired to include pitch or like bituminous or hydrocarbonaceous mate-rial.

Claims: v

1. An improved article of manufacture composed of anw-underlying member of fibrous material having a layer of `asphalt thereon and having a metal coating: for said asphalt layer comprising a layer of metal particles embedded in said asphalt layer and a layer of metal particles moleculrrlyl
